By the removal of members 36 the supporting lugs 34 may beswung downwardly and pan 3| removed.

It is desired to deliver a fine spray of liquid such as water into thechamber formed by casing 28, and for this purpose a tube or conduit 31is provided, the same being shown as equipped with a regulating valve33. Tube 31 extends into the header 23b and the same is formed into aheating coil 31a therein. Tube 31 extends from the heating coil 310,through one of the tubes 230 as shown in Fig. l, and said tube thenextends through a strainer or filter member 33. From member 39 a tube 40extends to a. magnetically operated valve 4| and the tube 42 extendsfrom valve 4| to an electrical heating device 43. From the electricalheating device 43 a tube 44 extends into the end of the conical portion280 of casing 28 and terminates in a spraying nozzle 45 constructedandarranged to deliver a very fine spray lengthwise of the casingportions 28b and 280 into the chamber thereof and over the plates 21.AMercoid or thermostatically operated control device 46 is mounted onthe header 23a and is suitably connected to the magnetically operatedvalve 4|.

In Fig. 16 the wiring diagram for the apparatus described is shown, andthe magnetically operated valve 4|, the electric heater 43 and theMercoid control or thermostatically operated control device 46 areshown. Line conductors 41 and 48 are shown which will extend to somesuitable source of electric current. Conductor 41 connects with aconductor 49 which extends to and is connected with the mechanism ofmembers 4| and 43. Another conductor 50 is connected to members 4| and43 and'a conductor is connected to conductor 50 and extends therefrom tothe control member 46. It may be stated that the valve 4|, the heater 43and the Mercoid control device 46 are now standard pieces of apparatusand are commercially made and sold,

and no specific description thereof is necessary,

beneath the loweras the specific constructionthereor forms no part ofthe present invention. The control device 43 is governed bythetemperature of the beating medium in the heater 23a and so govems'thevalve 4|, that noliquid is permitted to pass through tube 42 until adesired temperature is reached in the header 23a. The electric heater 43is also controlled so thatit will permit the passage of when the liquidhas been heated to a certain temperature.

. In the operation of the devicedescribed, a heating medium such assteam or 'hot water will be supplied through-pipe 24 to the header 23a,and the same will pass through the tubes 230 to the header 23b and outthrough, the return pipe 24. The plates 2'! will thus be heated. Whenthe temperature in header 23a rises to a certain degree, the controlmember 46 opens the valve 4| and liquid is supplied from tube 31 to theheater 43. This heater will be then operated to heat the water to adesired predetermined degree and the water will pass from heater 43 tothe nozzle 45 and will be directed in a'very finemist or spraylongitudinally of the chamber in member 23 over the plates 21. It willbe understood that tube 31 is connected to some source of vwater underpressure, such as the city mains. Air will rise through the bottom ofthe casing 20 and will pass into the bottom 'of casing 28. This airrises and passes through slots 3|d between the plates 21 around thetubes 23c and passes through casing 28, thus passing through the finemist or spray in said casing. A..great deal of moisture is absorbed bythe air and the air passes out through of the moisture collectingthereon, and the air passing over the plates will pick up thisevaporated moisture and will assist in the evaporation. The air is thushumidified by its cooperation with the plates 21 as well as by passingthrough the cloud of mist or spray in the casing 28. The air passesthrough a comparatively large inlet'opening into the casing 28 and dueto the fact that the outlet opening 28a is smaller, the air is confinedin the casing 28 for a time, thus somewhat raising the pressure on theair and the temperature thereof. The air is of course heated by thetubes 23c and heated and humidified air is thus supplied to the rooms.The device thusacts both as a heater and humidifier.

When the humidity in the rooms to be heated falls to acertain degree, or the temperature falls to a certain point, humidostatI50 or thermostat I41 will operate, depending upon which is being used,and motor 69 will be started and magnetically operated valve 81 will beoperated to permit flow of fluid through tube 84 and nozzle 89. It willbe understood that at this time the switch I44 will have its movablemember in contact with the side connected to either the thermostat orhumidostat, depending upon which is beingused. Air will now bedischarged from fan casing 61 into chamber 66 and this airwill passthrough the openings tween plates I8 and over the tubes 10c upward intothe chamber in casing 6|. divided spray will be discharged of the casing6| from nozzle 89, the Ever the plates'18. The air passing through thelongitudinally casing 6| will absorb quite a lot of the moisture fromthe spray. The liquid sprayed will descend I46 to a thermostat I41 I48and I49 to a huthemovable member of magnetiextend respecin" pan' 19 be-5 spray passing 6. the end trough, from where it will pass out throughthe drain pipe I. Plates ll being heated, will evaporate moisturecollecting thereon, and the air passing between the plates will alsopick up this moisture and carry it out of casing 6 l charge portion Theair passes out through the disila and the same engages the bailie plates63 before leaving portion la. Should any drops of moisture be carriedalong with the air, they will engage bailie 63 and be prevented frompassing on out through conduit 82 and to the rooms. It will be seen thatan effective baffling efiect will be produced by the plates 3 and thelips 63a thereon. The air delivered from this casing 61 is guidedupwardly between the tubes 10c and between plates I8, since a continuouschamber is formed by the sides of the casing 60, plates 64a and plates64, thus guiding the air into casing GI. The rooms will thus be heatedand supplied with the desired degree of humidity. When the humidity hasreached the desired degree, or the temperature has risen to a certainpoint, the humidostat I" or thermostat I41 will again operate and motor69 will be stopped and the magnetically controlled valve 81 controllingthe nozzle 89 will be closed. The water is strained or nozzle 89, sothat no trouble will be experienced with such nozzle clogging. A veryeflective humidifying and heating effect is thus obtained. It will benoted that the liquid sprayed is heated by the heating coil 84a and isalso heated by the passage of tube 84 through the heating tube Illc. Theliquid therefore has very little. it any, cooling effect on the platesI8 or the tubes 100.

If the device is to be used as a cooling device and for supplying cooland cleansed air to the rooms, as is desirable in hot weather, then acooling medium such as cold water or some refrigerant will be suppliedto the member 1|! through pipe Ila, valves 13 and I2 at this time beingopen and the valve in pipe llc closed. The cooling medium will pass intothe header 10a through the tube 10c and into the header 1012, from whereit will pass out through return pipe 14 and to return main 16a, valve 11being closed. When the temperature rise beyond the desired degree,thermostat 1 will operate, the movable member of switch I at this timebeing connected to the side connected to the thermostat. The motor isstarted, and the magnetically operated valve 81 will be operated and thespray will be directed into the casing ii. The liquid in tube 84 will becooled and said spray will be cold. The plates 18 will be cooled by themedium in the tubes 10c and air will be discharged from fan casing 61into chamber and around the tubes 10c and between plates 18 and into thecasing 6i. This air passes through the spray in the casing 6i and willpass out through the discharge portion Gla, the same striking andpassing between the baille plates 63 where any excess moisture willberemoved. The air is effectively cooled, washed and dehumidiiied, and theair is discharged into the rooms. The cold spray and cold tubes 10c andcold plates 10 will precipitate the vapor in the air and the air will becooled and the humidity greatly reduced. Any moisture draining fromplates 18 will drain into the troughs in pan 19 and will pass outthrough drain pipe 80 as already described. The temperature is thus keptat the desired point and fresh cooled and cleansed air is supplied. Whenthe temperature drops to the desired point, therfiltered as it passesthrough stop'ped and the valve II will shut oi! the no:- zle 9.

In the operation of the device shown in Figs. 7 and 14, when the deviceis to be used as a heat-- ing and humidiiying unit, heating medium-willbe supplied from the heat supply pipe III, valve I22 being open. Thedevice can be controlled by either the thermostat ill or the humidoatatm as desired. Switch l will be thrown to place one or the other inoperative position. When said member, operates, motor I will be startedand the control member Ill will be operated, as will also themagnetically operated valve 134. The heating medium will thus not besupplied until the temperature or humidity in the rooms falls below acertain point. The heat-.1 ingmedium is supplied to member Ill and'tubes lllc will be heated. The motor ill will operate the fans incasings I39 and air will be directed into chamber 98. Heat is alsosupplied to the radiator ill and the tubes lillc and the plates 0d willbe heated.

The air passing into chamber 88 is heated by the additional radiator illand this air then passes upwardly through openings lflc in pan I" overand between the plates I01 and tubes |00c.. Spray is directed intothe'casing 83 by nozzle I38 and the action of this spray on the platesllil' and the cooperation of the air therewith will be as alreadydescribed in connection with the device as shown in Figs. 1 and 6, andthe air will pass out of casing 93 after encountering the baflle plates9|. The liquid for the -spray will be .preheated by passing through theheating coil lilo and by the tube I30 passing through the tube llilc.The electric heater I" will be controlledso ther heated to have acertain temperature before it, can be discharged from nozzle I38 intocasing 93. A very effective atomization is thus produced, and a goodevaporation of the liquid on the plates I" is had. A clean, heated andthoroughly humidified air is thus delivered to the rooms.

When the cooled, cleansed and dehumidified air, a coolmostat I41 willoperate and motor 69 will be mg medium will be supplied to the membersIll and H0, this cooling medium being supplied through pipe 9, valve being open. The device will preferably be controlled at this time by thethermostat I", switch I being set to put the thermostat in operation.When the certain point, thermostat I" will operate and v the motor IIIwill be started. Valve Ill will be opened by control member II! and themagnetically operated valve I" will be operated. The heater l3 will atthis time be cut out of operation. Air will be forced pass the memberIll, said air passing between the tubes llllc and the-plates lid. Theair is thus initially cooled and the same will pass upwardly through theopenings Inc in pan I and between plates Ill and tubes "to. A cool spraywill be delivered into casing 83, some of which spray will descend andcollect on plates lll. These plates will now be cooled by the medium inthe tubes lllic and the air passing between .the plates will also becooled and the humidity therein reduced and this air will pass throughthe cold spray in chamber 93, being here further cooled. It will beunderstood that any moisture draining from plates I" will be caught inthe transverse troughs Illa and will pass that the liquid will befurdevice is to be used for supplying into chamber 98 and will and iseasily made and installed' through the side troughs I080 to the'endtrough lllb, from which it will drain out through the drain pipe "8d;The air is' forced from casing 93 and will encounter the baille plates94 as it leaves thecasi-ng, where any excess moisture willbeing used tocool the air, by the humidostat.

Such conditions might arise in industrial plants where it would beconsidered more important to control the humidity than the temperature.The devices shown in Figs. 6 and 7 could thus be op-- erated as coolingdevices, and switch I 44 would be disposed as desired to place eitherthe humidostat or thermostat in operation.

From the above description it is seen that applicant has provided asimple and efficient apparatus adapted to be used for heating andhumidifying the air in a room, and also adapted for, supplying a cooled,clean and dehumidifled air to the rooms. The device can thus beeffectively operated in either winter or summer. The device can beeilectively operated for supplying cool and dehumidified air by usingcold water or a special refrigerant, The water in the usual city mainsof some cities is sufllciently cool to secure a very eifective coolingand dehumidifying of the air, even in hot weather. The deviceillustrated in Fig. 1 can be installed in the rooms as an ordinaryradiator. The device shown in Figs. 6 and 7 will preferably be installedin a room or rooms other than the room to which the air is delivered andthese devices will be arranged to de iver air to a plurality of rooms.Such devices will usually be installed in a basement room.

The device is quite simple in construction, The device is quitesensitive and can be controlled to regulate the temperature and humidityin the rooms within very small limits. The same is entirely automatic inoperation and requires no operator in attendance. The device has beenamply demonstrated in actual practice, and found to be very successfuland efi'icient. i
